With the continuous enhancement of human environmental awareness, environmental protection laws and regulations are also being introduced and improved. All industries are working together in the direction of environmental protection, green, healthy.With the development of flexible packaging industry, it has become an inevitable trend to reduce and remove the organic solvents used in the compound.W...
I.Overview: Refilm process is widely used in all kinds of packaging, small to medicine box, artifact box, large to outer packing boxes and various product packaging.The current recoating technology includes precoating, dry recoating and wet recoating.Wet composite uses water-soluble adhesive cold paste process. Dry composite traditional composite film process is to apply solvent-based adhesive dir...
Choice of water-based adhesive Application index Some packaging and printing enterprises reflect that some water-based adhesives will degummy soon after gluing; Viscosity is not stable, sometimes bond firmly, but sometimes not bond; It works well in hot weather, but it doesn't work in cold weather.In fact, this is due to the lack of understanding of water-based adhesive application indicators. The...
1.The role of acrylic resins in photocured inks.Acrylic resin is widely used in the manufacture of photocuring inks because of its unsaturated property and polymerization reaction under the action of ultraviolet light.It and other substances, such as polyether, carbamate, polyester, epoxy resin, modified epoxy resin, poly caprolactam copolymer, can be used as a photocuring ink resin component. 2.T...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water-based viscosifying emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the bonding strength and initial adhesion of pressure sensitive adhesive on high and low energy surfaces, so as to achieve the best balance point, and can improve the application range and grade of pressure sensitive products. Today, we will take you to understan...
Water based adhesive Water-based adhesive refers to the water-soluble polymer dissolved into appropriate concentration of aqueous solution, or insoluble polymer dispersed into micro-particles (emulsion) in water with the help of surfactant in the general term of adhesives;In simple terms, adhesives made of materials that can be dispersed or dissolved in water are aqueous adhesives and are often re...
With the continuous improvement of people's demand for life, glue and adhesive products are also advancing with The Times and constantly upgrading to meet people's needs. The emergence of removable glue greatly satisfies this phenomenon, so what is removable glue? What are the characteristics of removable glue? Removable adhesive is a new type of environmentally friendly synthetic material, the ap...
Composition of adhesive Adhesives are adhesives that can bond two objects together, referred to as glue. There are different types of adhesives according to different divisions, the use of adhesives is also quite extensive, and now it has been filled in our lives, for adhesives, do you know how it is composed? How adhesives are composed: Synthetic adhesive Synthetic adhesive is composed of main ag...
Water-based pressure-sensitive adhesive is a type of adhesive that uses water as a solvent and is pressure-sensitive, that is, it can adhere quickly to the surface when slight pressure is applied. Due to its environmental protection, non-toxic, cost-effective, adjustable viscosity and other advantages, it has gradually become the mainstream product in the pressure sensitive adhesive market. Accord...
Let's take a look at the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of the aqueous acrylic emulsion contributes to the flow and wettability of the molecular chains on the surface of the substrate, making the coating and the substrate molecules in close contact to achieve high adhesion. 2.The high bearing capacity of the filler can significantly redu...
How to color printing ink? In the printing process, many of the color of the sample ink can not be used directly, the need for production enterprises to deploy according to the color of the sample, this process is called the color matching of the ink, and the printing plant is called the ink mixing. The color of printing ink is very important for printing, and it is also a difficult problem.The co...
The adhesive not only needs it to stick firmly, but also needs long-term viscosity, the effect of the adhesive is better, if it can not be sustained, after a period of time it will fall off, or for some reason, the viscosity will decline, so we sometimes need to think of some ways to ensure the durability of the viscosity. Research work and experience have shown that adhesives can bond things by i...
This new type of environmentally friendly water-based coating adhesive does not contain any organic solvent, has passed the SGS international certification, so it is non-toxic, there is no flammable, explosive danger, please rest assured that the manufacturers in the industry use. Water-based laminating adhesive does not contain toxic heavy metals, in line with the relevant packaging laws and regu...
As we all know, printed laminating is one of the surface decoration processing technology of printed matter, which is the auxiliary process of printing. It is the plastic film bonded together with the printed matter through the adhesive to improve the surface gloss, strength and aesthetic effect of the printed matter, so as to make it water resistant and wear resistant, which is an effective means...
First, the print composite bond is poor 1.Check whether the printed matter itself belongs to special paper; 2.Whether the printing ink is caused by excessive auxiliary materials or special ink; 3.Small amount of glue; 4.Low temperature or small pressure of hot press roller; 5.BOPP membrane corona is processed Second, the brightness of printed matter is poor after composite 1.Printed matter itself,...
